Effects of endotracheal tube and laryngeal mask airway on postoperative pulmonary complications in general anesthesia

Postoperative pulmonary complications (PPCs) after general anesthesia surgery significantly affect patient prognosis. However, there′s insufficient evidence to confirm if different airway management tools influence PPCs. Airway management tools used in general anesthesia surgery can be divided into two categories: supraglottic and subglottic. Among them, the laryngeal mask airway (LMA) and endotracheal tube (ETT) are typical representatives and are the two most widely used airway management tools in general anesthesia surgery. Therefore, it is necessary to review and evaluated the effects of these two mainstream airway management tools in general anesthesia surgery on PPCs, thus providing a theoretical basis for the selection of airway management tools during general anesthesia surgery in clinical practice.
